Segmented Sound Enclosure for Compressor Noise Attenuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
HVAC system compressors generate operational sounds that can migrate through refrigerant lines and be emitted radiantly, causing noise pollution and disrupting system operation.
Innovation Solution
A sound enclosure with a three-piece or two-piece construction, including side sections and a bottom section, designed to enclose the compressor and attenuate operational sounds by using overlapping sections, openings for refrigerant lines and junction boxes, and sound isolating devices to impede sound transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a sound enclosure is designed to completely enclose the compressor, then sound attenuation is improved, but access for refrigerant lines and electrical connections becomes difficult
Solution Approach 1:
The sound enclosure is divided into multiple separable sections (first section, second section, third section) that can be assembled and disassembled. This segmentation allows the enclosure to provide complete sound attenuation when assembled, while enabling easy access to the compressor by disassembling specific sections for refrigerant line installation and electrical connection access.
2Ease of operation
If the sound enclosure uses multiple separate sections, then ease of assembly and access is improved, but structural complexity increases
Solution Approach 1:
The enclosure is divided into three main sections that can be independently manufactured and assembled, simplifying the assembly process and enabling easy access. The segmentation is designed with simple joining mechanisms that reduce the overall complexity despite having multiple parts.
Solution Approach 2:
The sound enclosure is designed with multi-functional features: it provides sound attenuation, structural support for the compressor, mounting surfaces for electrical components, and integrated pathways for refrigerant lines. This multi-functionality reduces the need for additional separate components, thereby reducing overall structural complexity.

AI summary
A sound enclosure of a compressor to attenuate an operational sound level of the compressor is disclosed. The sound enclosure may be configured to generally enclose the compressor and attenuate radiantly emitted sound by the compressor. The sound enclosure may be configured to include a plurality of assembly sections, particularly two side sections and one bottom section, where the two side sections can be joined together like two halves of a clam shell and joined to the bottom section to facilitate easy assembly. The sound enclosure may form openings at longitudinal ends of the sound enclosure to accommodate refrigerant lines. The assembly sections of the sound enclosure may include one or more openings to accommodate a compressor junction box, wire bundles, oil lines, mounting mechanisms, etc.
